Abstract (en)

[origin: WO2019088888A1] A method for generating a probability map for a cell served by a network node is provided. The method includes generating a first probability map (P1) indicating a likelihood of primary beam directions (step 602). Generating the first probability map includes recording a first direction of a first user equipment (UE), the first direction indicating a direction of a first beam (e.g., a first set of antenna weights (a.k.a., precoding vector)) associated with the first UE when the first UE appears in the cell served by the network node. The method further includes generating a second probability map (P2) indicating a joint likelihood of primary and secondary beam directions (step 604). Generating the second probability map includes recording a second direction of a second beam associated with the first UE when the first UE switches from the first beam to the second beam, the second direction being recorded in association with the first direction. 28 3602-1538WO1 (P73007WO1)
